To (all 'L11/unit /15 'ntfty/ (e0/weint:

Be it known that L Ronun'r E. H. WUR- DIsCH, a citizen ot' the United States, residing in the city and county ot' San Francisco and State of California, have invented new and useful improvements in DumpWagons, ot' which the following is a specification.

My invention relates to a wheeled vehicle having a body adapted to carry loose material and connections by which said body may be so disposed as to discharge its load and to again be returned to its normal position.

My invention comprises a combination of mechanism wherebythe vehicle-body is raised into an inclined position, moved into a posi? tion to tilt and discharge its load, and return it again to its normal position.

lit also comprises details ot' construction which will be more i'ully explained by ret'erence to the accompanying drawings, in wl'iieh Figure 1 is a side elevation with body in normal position. Fig. 2 shows body tilted. Fig. l) isa partial section ot' gate and latch. Fig. 4 is a bottom View otl same. Fig. 5 is a side View otl front ot' body raised. Fig. 6 is a vertical section of saine. Fig. 7 is a perspective view ot' winding-drum and clutchsleeve. Fig. 8 is a plan view ot' same. Fig. 9 is a modilication otl tail-gate mechanism.

.lt is the object oi' my invention to provide a wagon or vehicle having a permanent bed and running-gear, with a body adapted to carry coal, ore, or any material which it is desirable to discharge from the body without handling, and in combination with said vehicle parts ot' mechanism by which the body may be raised into an inclined position, allowed to run backwardly by gravitation and to tilt and discharge its load, and then to be returned to its normal position ready `lor another load.

As shown in the drawings, t represents a bed-frame or running-gear ot any suitable or desired description. lVhen used tor a roadvehicle, it will be mounted upon wheels B, with the'usual connections for a team by which the wagon may be hauled from place to place. lli adapted to a mining-car, the construction ot' the bed or wheels will conform to the tracks or whatever support the car may be designed to run upon. s

Hinged to the rear portion of the frame A is a frame 2, which may be raised or depressed about its hingepoint. in its normal position it stands substantially parallel with the frame A and between the side timbers ot this trame.

The front end of this trame 2 is adapted to be raised by mechanism to be hereinafter described, so as to stand at a considerable angle, and the wagon-body 3 is so mounted upon this frame that when the trame is raised into the inclined position the wagon-body may slide hackwardly upon the frame.

ft represents rollers loosely journaled upon a shaft carried upon the rear axle-bed, and the longitudinal timbers of the body 3 are adapted to travel upon these rollers, so that the body may be slid backward and :lorward with ieast friction. At the Jr'ront end o't the body are other rollers journaled, as at 5, so as to rest upon the frame-timbers 2, and the plates in which the rollers are journaled may be eX- tended downwardly upon each side of the timbers, as at 5, so as to prevent side motion of the body or the displacement of the rollers from the timbers on which they travel. rl`he rollers L being langed will perform a like oliice Yfor the rear end o1" the body. and in addition to this I have shown hook members 6 extending upwardly upon each side otl the bottom timbers ot the body 8 and contiguous to the rollers 4.

Upon the side of the bed-timbers A are lixed vertically-slotted plates, as at 7, and upon the sides of the bottom timbers oi the body 3 are iixed pins, as at 8, which project so that when in line above the slots in the plate 7, the body being then in an inclined position, the body may be let down by the actuating mechanism and the pins will enter the slots in thc plates, thus locking the body and prcventing its running backward or forward. When the body is allowed to move backwardl y to the point where it will tilt and discharge its load, the pins 8 will contact with and be arrested by the hooks 6, thus {.)reventing the body from traveling any farther to the rear, and in this position the body may tilt to suchA an angle as to discharge its load by gravitation. The incline of the timbersQ when raised into position `for the body to run back and discharge is sui'licient to lift the pins 8 out ol. the slots in the plates 7 and above the rear side of the slots, so that when the body is reare stout bars 10. and these bars when the gate is closed fit into slots 11, made in the rear part of the bottom of the vehicle, the bars projecting slightly below the bottom. Pivoted beneath lthe bottom are latches 12. The inner ends of these latches are each bent inwardly at an angle, as shown, and are pressed upon by springs 13, so that when free the outer ends of the latches will hook over and engage with the lower ends of the bars 10, thus holding the tail-gate in a locked position.

The releasing mechanism consists of a. slidable bar 14, moving in guides and having rollers or other antifrictional contacting-surfaces at the ends, which when the bar is drawn forward will press against the angular portions of the hook-levers and pressingl them both out of their normal position against the tension of the springs 18 will disengage the hooks 12 from the bolts 10, thus releasing the tail-gate. The bar 14 is connected by links, as at 15, with a rocker-arm 16, connected with the shaft 16, which is journaled across the lower part of the wagon-body, as shown. A lever 18 is fixed to the outer end of this shaft, projecting up along the side of the body of the vehicle and is connected by a rod 19 with the hand-lever 20, pivoted upon the side of the wagon-bod y and extending up to within easy reach of the driver. A suitable curved rack 21 serves to hold the lever in any desired position.

Extending rearwardly from the upper end of the rocker-arm 18 is a link 22, having its rear end connected with pins projecting from the side of the tail-board 9, and -its front end has aslot made in it, as shown at 23. Vithin this slot the upper end of the rocker-arm 18 will move during the first portion of the movement of the lever 2() and of the rockerarm 18. This allows the rocker-arm 16 to act through the link 15 upon the slide 14 to first disengage the hooks 12 from the pins 10, thus releasing the gate. The further movement of the rocker-arm 18 brings its upper end into contact with the rear of the slot 28, and it then pushes upon the links 22, one on each side of the body, and turns the tail-gate about its hinge-rod at the top, so as to swing it upwardly and leave the rear end of the vehicle openand free.

The movement by which the frame 2 is raised from its normal position into an inclined position which will allow the body to run rearwardly is effected by means of drums 24. These drums are here shown as loosely turnable upon a central shaft extending beneath the vehicle-seat or at other convenient point at the front, and upon the same shaft is an inner drum 25 also loosely turnable. The drums 24 have flexible bands or ropes adapted to coil upon them, and the ends of these bands are connected by links with the front end of the tiltable frame-timbers 2, so

that when these drums are revolved to wind up the flexible bands the front ends of the timbers will be lifted until they are in the proper inclined position, and this will raise the pins 8 out of the channels in the slotted plates 7, so that the body is free to move backwardly, as previously described.

The inner drum 25 has wound upon it ropes` or flexible connections, the ends of which are connected with the lower part of the body For convenience in operating these ropes may pass around guide-pulleys 26, and when the inner drum is released, the body being in the inclined position, the ropes will be free to turn to unwind from the'drum and the body will run backwardly upon its inclined support until the pins 8 are stopped against the hooks 6 and the body is in position to tilt and discharge its load. In order to operate the outer drums 24 and the inner drums 25 indedendently of each other, I have shown a clutch 34, located between the outer and the inner drums. This clutch is here shown in -the form of a sleeve 34, turnable with the shaft 34, and in the ends of the sleeve pawls 27 and 33 are pivoted so that they may be moved to engage with either the outer or the inner drums.

The pawls are here shown as pivoted upon the sleeve 84 andare acted upon by springpressed pins 28, slidable within the sleeve and acting normally to force the points of the pawl 27 into engagement with a corresponding notch on the end of the drum 25. In this condition the drums 24 may be revolved to raise the frame 2 by turning the shaft 34a in one direction, and as it is desired to revolve the outer drums 24 first in order to raise the supporting-timbers 2 and the body to stand at the required angle to cause the body to move backwardly the pawl 27 is disengaged from the central drum 25 by the pressure of a lever 29, which is fulcrumed in line with the slot in which the pawl 27 stands diagonally between the drum 24 and the sleeve 84,

and when this lever is pressed down it enters the slot or channel and in this position stands in line, so that when the sleeve begins to turn the drums 24 the pawl will be forced back and out of engagement with the drum 25. The drum 25 will be held in place and prevented from turning by means of a bandbrake 30, which is actuated by a foot-lever 31 within convenientreach of the driver. This foot-lever being' pressed down brings such tension upon the band-brake as to prevent the central drum from revolving. The outer drums may then be revolved by means of a bevel-gear 82, fixed upon the outer end of the vemea shaft, and a clutch formed by a spring-pressed pawl 33, engaging' the outer drum with the sleeve 3st, which is fixed to the shaft between the drums 24 25.

A convenient connection for the driver is by means of a vertical turning shaft 35, with a handle or wheel upon the top and a pinion 36 engaging' with the gear-wheel 32. Thus by turning this shaft, and through it the gears, the pawls 33 of the clutch member will engage the drums 24, and when the drums are turned round by the application of power the flexible bands connecting' with the tiltable bars 2 will be coiled upon the drums and the front end of the bars 2will be raised into the desired inclined position. Ratchet-and-pawl mechanism, as shown at 37, serve to hold these drums and retain the timbers 2 in their inclined position. rlhe body 3 is then in readiness to run backwardly by gravitation whenever released. T his release is effected by disengaging the band-brake by means of the foot-lever 31, and as the pawls and ratchets 37 prevent the drums 2a from revolving, while the central drum 25' is free to revolve, it will be manifest that the timbers 2 will be held in their inclined position, while the drum 25 revolves freely, allowing the ropes to unwind until the body has reached the position in which it will tilt, the gate having' been opened previous to raising the frontend of the body into its inclined poe sition. The load having been thus discharged, the central drum may be wound up as follows: By turning the winding-shaft 35 in the opposite direction from the movement required to raise the body into its inclined position the clutch-pawls 33 will move freely past the notches in the drums 24C, which they engage when moving in the opposite direction. The first revolution of the clutch-sleeve 34e will cause the pawl 27 to raise the lever29 by reason of the rear portion of the pawl contacting with the lever as it passes beneath it, and the lever will thus be raised out of the way of the pawl. rlhe spring by which the pawl is pressed will then force the pawl to engage with the drum 25, and the winding-up of the ropes which draw the body forward will thus be eifected. The body will be first tilted forwardly upon the supporting drums or rollers 4t, and when its front end rests upon the inclined tim bers 2 the continued revolution of the drum 25 will wind the ropes up `until the body has been brought forward, and the pins 8, contacting' with the front sides of the slots in the plates l7, will arrest this forward movement. The foot-lever 3l being then pressed down, the band-brake which it actuates will iirmly grip the drum 25 and prevent its again unwinding to allow the body to run backwardly. rlhe pawls which engagethe ratchets at 37 may be then lifted by means of a connecting rod or link 40, the lower end of which is connected with a rockerarm mounted upon a shaft 39, and this rocken arm and one at the opposite end of the shaft act as lifters, so that when the link or rod is pulled upwardly the pawls will be disengaged,

and the drums 2Liwill then be free to revolve and allow the timbers 2 and the body resting upon them to sink to their normal and ap' proximately horizontal position. The rear gate being' closed by movements opposite to those which opened it, the body will be in readiness to receive another load.

ln llfig. 91 have shown a means for moving the tail-board 9 forward as it opens, so as to insure a better clearance for the discharging load. ln this construction the upper edge of the tail-board is pivoted to the end of levers 9, and these levers are fulcrumed, as at 9b. The opposite ends of these levers are connected and movable with the links .22, which may be slotted for the purpose. The movement of levers 22 to push the tail-board up also swings the levers 9 to simultaneously pull the tail-board forward as it tilts upward.
